Can't get it to work in bundled mode (RN in existing Android app) about react-native-exception-handler

[a7ul]

@ChristofferKarlsson Hi. I see you have added setJSExceptionHandler(errorHandler, true). This will not show the red screen in debug mode. Can you help me with a screen shot of the exact error you are getting ?

[ChristofferKarlsson]

@master-atul Sure! I am running in debug mode now, in the Android emulator, but I'm only getting the RN red alert. None of the custom alert box.

I'm forcing the error by calling an undefined method this.aaaaa().

@ChristofferKarlsson From your screen shot.. it seems like the react native exception module is not initialised. Can you confirm if you have imported xyz.js which contains the setJSExceptionHandler() into your main program at the very beginning ?

[ChristofferKarlsson]

@master-atul Yes, it gets imported there. It's in the same file I call the undefined method. I have tried to move around the setJSExceptionHandler() in the app, but it makes no difference.
Can I do some debugging in the Android-project to see if it gets initialised?

Edit: Now I somehow get the Alert box again. But the RN red alert screen is always put over it, so I need to dismiss that one before being able to see the custom alert box.

I have now reinstalled and cleaned everything twice. After the second time I got it to work! Sorry for the inconvenience.

Great ! Thanks for posting it that it works!
